I ran across this too early on. If you rebuild your kernel and build in the option <boot kuwi 100 first> it should fix it. BTW im working off memory here the option should look similar but not exact. I'm pretty sure it's in the same section as most of the other mac powerbook options. Let me know if you still can't find and ill look it up for you. Also, tell me what kernel version you are using as well. NOTE: don't forget to reset the yaboot stuff back before rebooting. Good luck!
